Intelligent Stud Finder

FIG. 1A is a perspective view of an embodiment of an intelligent stud finder 10. In an embodiment, the intelligent stud finder 10 can have a sensor paddle attached to a handle 30. Herein, the term “intelligent stud finder” and “stud finder are used synonymously”.

The stud finder 10 can be turned on and off by a switch 12 which can be a toggle (non-momentary) switch which be or a momentary switch. In an embodiment, the switch 12 can be pushed on, switched on, or toggled on and the stud finder 10 can stay on until the switch 12 is pushed off, switched off or toggled off.

FIG. 16 is an example of a starting position projected over a stud.

In an embodiment the stud find can be calibrated without Moving.

Optionally, the stud finder can be configured to not display any lighted LEDs when initially placed on the wall 3500, target surface, or other surface to be sensed for studs, conduits, or other sources of changes in capacitance. Herein, the wall 3500 is used as an example of a target surface. The technology disclosed herein can be used to hang objects on a wide variety of target surfaces which can be made from a broad variety of materials, such as drywall, presentation boards, support structures, display structures, edifices, sets, scenery, or other support onto which an object and/or thing can be hung, all of which can be encompassed by the meaning of target surfaces as used herein.

In an embodiment, the stud finder will need to move 1 plate length in order to cause any LEDs to be lighted.

In an embodiment, the stud finder will need to see a capacitive plate increase in capacitance value of greater than the average noise value of capacitance readings, or a set point value of capacitance, in order to cause an LED associated with a capacitive plate to be lighted. In an embodiment, a set point difference in capacitance of 0.5%, or 1%, or 2%, or 3%, or greater, of the capacitance value of a capacitive plate when not sensing a stud can activate the LED associated with that capacitive plate to indicated that a stud has been sensed. In another embodiment, the set point value (also as “set point”) of difference in capacitance is a difference greater than the nominal difference between capacitive plates, or greater than the capacitance noise values of the capacitive plates.

In an embodiment, the stud finder can be limited to lighting a maximum of three (3) LEDs at any one time.

Example 1

In an embodiment, the stud finder can have a Beginning Operation method having the steps below.

Step 1: Place the stud finder on the wall 3500 and turn it on.

Step 2: Once the unit is on, the capacitive plates will send readings to the microprocessor. The microprocessor will compare the capacitive values and the plates with a higher value will indicate a stud. In this example, capacitive plates 2, 3, and 4 in FIG. 16 are over a stud so they will read a high capacitive value. Capacitive plates 1, 5, 6, 7, 8, and 9 are not over a stud so they will read low capacitive values in comparison to the values of capacitive plates 2, 3, and 4. The unit will not turn on any LEDs though aside from the power light indicator.

Step 3: The unit will only turn on LEDs when a capacitive value changes from low to high.

Step 4: As the stud finder is moved to the left, as shown in FIG. 16, sensor plates 3 and 4 remain high capacitive values and 1, 6-9 remain low capacitive values. Capacitive plate 2 is no longer over the stud so its capacitive value changes from high to low. Capacitive plate 5 is now over the stud so its capacitive value changes from low to high. Now that this change from low to high capacitive value has occurred on one of the capacitive plates, the Stud Finder will turn on the LEDs corresponding to the capacitive plates indicating high capacitive values.

Optionally, in an embodiment an accelerometer can be used in lieu of or in addition to capacitive plates. Once the stud finder is powered and placed on the wall 3500, the accelerometer will return a value of zero when the unit is not moving. Once the stud finder is moved along the wall 3500, the accelerometer will verify an increase in acceleration in the lateral direction, either positive or negative. The processor would then recognize that the stud finder moved. At this point, the stud finder will check capacitive readings and will send a signal to light the LEDs that are associated with the sensor plates with high capacitive readings.

FIG. 17 shows the movement of the stud finder to activate the LEDs projected over the stud.

FIG. 18A is a logic flow diagram for an example of a no stud operation.

FIG. 18B is a logic flow diagram for an example of a stronger capacitive value operation.

When two separate groups of sensor plates indicate high capacitance, the unit will compare which group of values are higher, and display those LEDs. In the situation above, the left group of capacitive values has higher values than the right group of capacitive values, so left group of LEDs are displayed.

FIG. 18C is a schematic showing a result when the capacitive plates over a first stud have higher values that the capacitive places over a second stud.

FIG. 18D is a logic flow diagram for an example of a random operation. When two separate groups of sensor plates indicate high capacitance, the unit will randomly select one of the groups and display the LEDs of the selected group.

FIG. 18E is a schematic showing a result when the capacitive plates over a first stud have a high capacitance and the capacitive places over a second stud also have a high capacitance.

FIG. 18F is a logic flow diagram for an example of a first (left) stud operation. When two separate groups of sensor plates indicate high capacitance, the unit will display the left group of three LEDs.

FIG. 18G is a schematic showing a result when a first stud have a high capacitance and the capacitive places over a second stud also have a high capacitance and three LEDs projected over the first (left) stud are lighted.

FIG. 18H is a logic flow diagram for an example of a second (right) stud operation. When two separate groups of sensor plates indicate high capacitance, the unit will display the right group of three LEDs. Optionally, when two separate groups of sensor plates indicate high capacitance from being projected over separated studs, the unit can have no lighted LEDs.

FIG. 18I is a schematic showing a result when a first stud have a high capacitance and the capacitive places over a second stud also have a high capacitance and three LEDs projected over the second (right) stud are lighted.

FIG. 18J is a logic flow diagram for an example of a first stud operation. When two separate groups of sensor plates indicate high capacitance, the unit will always show the first stud it encountered. For example, in FIGS. 18K2 and 18K3, the stud finder senses both studs but remains showing the first stud and the first stud only.

FIG. 18K1 is a schematic showing the stud finder projected over a second stud.

FIG. 18K2 is a schematic showing the stud finder projected over the earlier encountered second stud and a portion of a later encountered first stud.

FIG. 18K3 is a schematic showing the stud finder projected over both the earlier encountered second stud and the later encountered first stud.

FIG. 18L is a schematic showing no LEDS when two separate groups of capacitive plates each indicate high capacitance. Optionally, when two separate groups of sensor plates indicate high capacitance, the unit can display no LEDs.

FIG. 18M is a logic flow diagram for an example edge of stud operation for the intelligent stud finder.

Example 2

In an embodiment, the stud finder can have an Edge of Stud Finder Operation method having the steps below.

Step 1: When the sensor plates do not indicate any plates with high capacitance, the unit will not display any LEDs

Step 2: As the unit approaches the edge of a stud, the outside edge sensor plate (sensor plate 1) will change from low to high capacitance and the corresponding LED will turn on

Step 3: As the unit moves further across the stud, the second sensor plate will also change from low to high capacitance and the corresponding LED will also turn on

Step 4: Only the 2 sensor plates on each end can display their LEDs without being a complete set of three. If only one or two central sensor plates indicate high capacitance but the other adjacent sensors indicate low capacitance, than the three closest LEDs to the central highest capacitance value will turn on.

FIG. 25 is a logic flow diagram for a separated stud operation for the intelligent stud finder.

Example 3

In an embodiment, the stud finder can have a Two Separate Stud Operation method having the steps below.

Step 1: When two separate groups of sensor plates indicate high capacitance, the unit will display the left group of three LEDs for 0.2 seconds.

Step 2: The unit will have a 0.05 second delay, displaying no studs.

Step 3: The unit will then display the right group of three LEDs corresponding with the right group of sensor plates indicating high capacitance for 0.2 seconds, and then have another 0.05 second delay displaying no studs before repeating.

In another example, when multiple studs are sensed, the stud finder can communicate the following display of LEDs:

Step 1: Turn the 3 LEDs associated with the left stud on for 0.2 seconds;

Step 2: Turn off all LEDs for 0.05 seconds;

Step 3: Turn the 3 LEDs associated with the right stud on for 0.2 seconds;

Step 4: Turn off all LEDs for 0.05 seconds; and

Step 5: Repeat, on optional number of times from once to many, or for as long as the stud finder is maintained in the activation position projected over the multiple studs.

FIG. 46A is a perspective view of the picture hanging device with a movable handle and two pivoting arms in an unfolded state.

In an embodiment, the picture hanging device can have a sliding handle. In the embodiment of FIG. 46A, the movable handle has a mushroom shape. However, the handle can be of any of a broad variety of shapes and designs.

The purpose of the sliding handle is to help the user adjust the height of the handle depending on the picture frame they are using.

Pictures have different sized gaps between the back support and the top of the frame, so the ability to adjust the handle to accommodate for these different situations would help the user to be able to use the picture hanger for many different sized frames quickly and effectively

The Sliding Handle works by having two locking pins or locking projections such as locking projections 2222. Optionally, one locking pin or locking projection 2222 can be used on each side of the central body of the picture hanger. The locking pins or locking projections 2222 can reversibly fasten into designated slots inside the back of the central body of the picture hanger. Once the locking pins or locking projections 2222 are secured into their slots, the sliding handle will not move achieving a hand support for the user to hold on the picture hanger allowing the user to maintain the picture in a desired position steadily against the wall 3500

When the user wants to adjust the height of the sliding handle, they just compress and hold both grips, such as fingers 2221, in. This will release the locking pins or locking projections 2222 from their fastened position and allow the user to adjust the height of the sliding handle. Once the user has reached the new desired position, they release the grips, such as fingers 2221, and adjust it so that the two locking pins fasten to the closest parallel slots. The user can verify that these are the correct slots with the bubble vial on the sliding handle. Now the user can employ the handle again as a steady support for the next picture they will hang on the wall 3500.

FIG. 46B is a perspective view of an embodiment of a sliding handle. In an embodiment, a bubble vial 1800 can be used.

Herein, the reference number 4000 refers broadly to objects and things to be hung on a target surface or support, such as a wall, a surface, a structure, edifice, display or other target on which to hang something. The objects and things which reference number 4000 encompasses can, in nonlimiting example, be any one or more of a: material thing, a tangible thing, a frame, a picture frame, an object of art, an artistic work, a furnishing, a decorative item, a display piece, knickknacks, bric-a-brac, a machine, an equipment, a clock, a mirrors, a lighting or other fixture, an ornament, a decoration, a drapery, or other item. The reference number 4000 encompasses, for nonlimiting example “picture frames”, also herein as “frames”, generally and in all shapes and sizes regardless of what subject matter is actually framed, e.g. a picture, a piece of artwork, a mirror, or other framed subject matter. Herein, a picture frame 4000 also includes a framed canvas or other support structure which is to be hung.

Single Support Process

Step 1: User can first find the appropriate location for the picture frame 4000;

Step 2: User places picture frame 4000 on the marking hook 2781 of the picture hanging device;

On wire hangers, locate the most central point on the wire and hook the wire at that location with the marking hook 2781;

On metal saw tooth hangers, attach the marking hook 2781 to the central gullet;

Step 3: Once the picture frame support (wire or metal saw tooth) is placed on the marking hook 2781, the user picks up the picture hanging device and puts it against the wall 3500 so the picture frame 4000 is in the desired location;

Step 4: The user now removes the picture frame 4000 from the marking hook 2781 with one hand while keeping the picture hanging device in place with the other;

Step 5: The user now presses on the marking hook 2781, which will leave and/or creates a dimple in the wall 3500, or marking on or to the wall 3500;

Step 6: The user will grab their hammer and a nail, and pound the nail into the dimple in the wall 3500 created by the picture hanging device;

Step 7: The user will place the picture frame 4000 on the wall 3500;

Step 8: The user will use a level to verify that the picture frame 4000 is straight;

Step 9: Now the picture hanging is complete.

Picture Hanging System

The picture hanging system allows users to visualize, plan, layout, and execute creative “gallery” arrangements of decorative items in their home.

The picture hanging system helps inexperienced users to visualize picture wall 3500 gallery. Offer inspiration in the form of attractive “suggested” arrangements.

The picture hanging system can be used with a wide variety of objects to be hung, e.g., picture frames, shelves, TVs, flat screen TVs unusually shaped objects.

In an embodiment, the picture hanging system provides instructions to the users and suggestions as to which tools to use to hang pictures on the wall 3500 to create the gallery per the visualized plan.

Optionally, the picture hanging system can display images of the tools that the use can use to realize the results that the app helped them to plan and visualize.

User Experience Step by Step: Visualization

User should take photo of the wall 3500 to be decorated. App should provide instructions on how to do it to allow the app to recognize the size of the wall 3500. User can be asked to indicate center of the arrangement in the photo.

App automatically saves image and ask user to make a photo of pictures (frames) to be arranged. App provides instruction how to do it to allow app to recognize size of each picture. App automatically visualizes new picture at the wall 3500 at scale. Repeat this step to accommodate all pictures.

In an embodiment, a user can photograph each framed object from a number of objects, or object to be hung, individually. The app and/or software can have a processor which executes executable program code having program logic which recognizes the dimension of each framed object. This processor and software can be customized to process the execution of executable program code having a rule-based logic to determine possible appropriate arrangements of the framed objects. The possible appropriate arrangements can be stored and called from an accessible computer memory, or can be entered by the user. When a user is to choose an appropriate arrangement from stored possible appropriate arrangements, then the user can select a desired arrangement. Once the user has selected the desired arranged, then the processor can process that user input, stored data and/or instructions regarding use of selected arrangement of the framed objects and/or objects.

The option to save images and add additional pieces to the existing arrangement should provide the opportunity for the user to visualize a potential new piece while still in the store before purchase.

At this point the app will offer the choice of automatic arrangement by App using “smart algorithm”. Herein, the term “app” or “App” in addition to its ordinary and customary meaning, is intended to encompass a computer software application(s), software, program code and executable program code and related logic which can be use or execute to achieve the embodiments disclosed in this application. The term “app” is to be broadly construed to encompass the computer software, code, executables and instructions to operate in conjunction with a computer processor and memory on a computer, computing device, phone, smart phone, digital device, personal digital assistant, camera, digital camera, video camera or other device which may be used for the purposes disclosed herein. The app can consider the actual pictures and/or objects a user intends to arrange and/or hang and can determine and suggest aesthetically pleasing arrangements to be executed by the user

Alternatively, the user can manually move pictures and app will help to keep them parallel to floor and provide equal spacing. The app should provide a “snap to grid” feature to aid in making the pictures aligned horizontally or vertically or to align items relative to center of picture.

App will allow the change of horizontal and vertical spacing in both modes. And move whole arrangement together in any desired direction.

In an embodiment, a user can use the app in conjunction with a variety of tools and object to achieve the end result shown by the app and/or chosen by the user, e.g. stud finder, laser level device 3600, picture hanging device, picture hanger, spacers 3800, and a measuring device.

In an embodiment, the user will be asked to hang the first picture as close as possible to the position of green mark on the gallery visualization screen. On the next steps the user can be taught how to arrange pictures based on position of first one. This will depend on mountings for picture frame 4000 and other variables

Another exemplary embodiment of a picture hanging device is shown in FIGS. 63-73. The picture hanging device 2000 of this exemplary embodiment is similar to the picture hanging device 1000 of FIGS. 35-52 and the present exemplary embodiment should be presumed to operate similarly unless otherwise noted. Additionally, the features of the exemplary embodiment of FIGS. 35-52 can be combined with or substituted for features of the present exemplary embodiment.

The picture hanging device 2000 of FIGS. 63-73 includes a main body portion 2100. A pair of arms 2500 are rotatably attached to the main body portion 2100. The arms 2500 can rotate from a vertical or closed position, as shown in FIG. 63, to the extended position shown in FIG. 64. Although FIGS. 63 and 64 show the two arms 2500 in similar deployments, the two arms 2500 can be rotated independently of one another so that one arm can be in the closed position while the other is in the extended position. As with the earlier embodiment, the present embodiment includes a pair of slide members 2700 which slide along the arms 2500.

The picture hanging device 2000 also includes a sliding handle 2200. The sliding handle is shown in more detail in FIGS. 46B-46K, mentioned above. As shown in those figures, the sliding handle 2200 includes a handle portion 2201 which can be gripped by a user. It also includes a number of fingers 2220 and 2221. The fingers 2221 have locking projections 2222, as shown. Additionally, the sliding handle 2200 includes a level indicator 2210, such as a level bubble vial 1810, which allows a user to determine when the device is level.

The fingers 2220 and 2221 slide on rails 2101 on the main body portion 2100. The rails 2101 have a series of notches 2102. When the locking projections 2222 of the fingers 2221 engage the notches 2102, the sliding handle 2200 is secured at a particularly location. In order to move the sliding handle 2200, a user can press the fingers 2221 inwardly (e.g., see FIGS. 46H1 and 46H2). When the user presses the fingers 2221 inwardly, the locking projections 2222 disengage the notches 2102 and can move along the rails 2101. Particularly, the locking projections 222 are disposed inwardly of the rails 2101. The user can then slide the sliding handle 2200 along the rails 2101 to a desired location. Once the user releases the fingers 2221, they can again engage notches 2102 in order to secure the sliding handle 2200.

As shown in, for example, FIGS. 63-66, the picture hanging device 2000 includes a storage drawer 2800 at the bottom of the main body portion 2100. The storage drawer 2800 includes a drawer portion 2801 and a cover 2802 which can be opened and closed. The storage drawer 2800 can be used by a user to store accessories such as nails, picture supports, screws, wire and the like. The cover 2801 includes a cover side latching member 2803 and the drawer includes a drawer side latching member 2804, as shown in FIGS. 70 and 71. As shown in those figures, the cover side latching member 2803 of the exemplary embodiment projects over the bump that forms the drawer side latching member 2804 in order to keep the cover 2801 closed. As will be appreciated, the cover side latching member 2803 can deflect and allows a user to open the cover 2801 when it is pulled with a sufficient force whereas when no significant force is applied, the cover will remain closed.

As shown in FIG. 63, the picture hanging device 2000 includes three markers 2780. Each arm 2500 includes a marker on the respective slide members 2700. Additionally, the main body portion 2100 includes a marker assembly 2780 at a lower central location above the storage drawer 2800. As shown in FIG. 65, the picture hanging device 2000 includes an anti-friction pad 2301 which is located on a projection 2300 which extends rearwardly from the main body portion 2100.

The picture hanging device 2000 of the present embodiment includes markers in a similar manner as the previous embodiment describing picture hanging device 2100. However, the marker assemblies 2780 of the present embodiment are constructed somewhat differently than the previous embodiment, as shown and described with reference to this exemplary embodiment. The marker assemblies 2780 include a marking hook 2781 at their front side. The marking hook 2781 includes a receiving space 2782 for a wire or the like. The marker assemblies 2780 further include a marker 2783 which is suitable for marking the wall 3500. In this case, the marker 2783 is made of metal and includes a point to make a mark on a wall 3500. However, other markers are possible, such as a marker that will produce an ink mark on the wall 3500. The marker can also be made of chalk or graphite to product the mark. In some embodiments, the marker can be replaceable and/or ink, chalk, graphite or other marking material of the marker can be replaceable. The marker can also be another hard material with a point that would make a mark on the wall 3500.

As shown in FIG. 70, the marker 2783 is surrounded by a sheath 2790. The sheath 2790 is biased towards the extended position shown in FIG. 70 by a spring 2784. Additionally, the sheath 2790 includes an opening 2791 sized and located for a tip end, such as the marker tip 2785 of the marker 2783 to protrude through the opening 2791 and mark a wall 3500. The marking hook 2781 and marker 2783 do not move relative to one another in order to expose the marker tip 2785. Instead, the sheath 2790 is movable relative to the rest of the picture hanging device 2000. Particularly, the sheath 2790 is biased by spring 2784 to the position of covering the marker end 2785, as shown in FIG. 70. When the picture hanging device 2000 is pressed towards the wall 3500, the sheath 2790 hits the wall 3500 and is compressed against the force of the spring 2784 to expose the marker end 2785. The sheath 2790 is shown in a compressed position in FIG. 71. As shown in FIG. 71, the marker end 2785 projects out of the opening 2791 and can mark a wall 3500 or other target surface.

In use, a user extends the arms 2500 to the extended positions shown in FIG. 64 and places the picture hanging device 2000 against a wall 3500. The user can adjust the location of the slide members 2700 along the arms 2500 as desired. As will be appreciated, the user can perform these steps in different orders. That is, a user can place the picture hanging device 2000 against the wall 3500 and then extend the arms 2500 or can extend one or more arms 2500 first and then place the picture hanging device 2000 against the wall 3500. Likewise, the slide members 2700 can be adjusted before or after the device is placed against the wall 3500. Once the slide members 2700 are slid to the appropriate positions and the picture hanging device 2000 is placed against the wall 3500, the user can use the picture hanging device 2000 to mark the wall 3500 with the marker assemblies 2780. In order to mark the wall 3500, the user pushes the picture hanging device 2000, particularly a lower portion of the picture hanging device 2000, towards the wall 3500. The lower portion of the hanging device 2000 can pivot around the projection 2300 with the friction pad 2301 so that the markers 2783 are moved closer to the wall 3500. As the markers are moved closer to the wall 3500, the sheath 2790 is moved by the wall 3500 in a direction of compressing the spring 2784. Accordingly, this exposes the marker end 2785 so that it can mark the wall 3500.

FIGS. 67 and 73 illustrate this operation of the picture hanging device 2000. Specifically, FIG. 67 illustrates the picture hanging device 2000 when the lower end of the picture hanging device is not pushed towards the wall 3500 and the sheath is covering the end 2785 of the marker 2783. FIG. 73 illustrates the picture hanging device 2000 in a marking condition where the lower end of the picture hanging device 2000 has been pushed towards the wall 3500. In FIG. 73, the sheath 2790 has been compressed to expose the end 2785 of the marker and the marker 2785 marks the wall 3500. The arms 2500 are removed in FIGS. 67 and 73 in order to illustrate the marking assembly 2780 located on the main body portion 2100. The remaining marking assemblies 2780 would work in a similar manner.

FIGS. 68 and 72 also illustrate a lock bar 2795 which is used to secure the sheath 2790 connected to the main body portion 2 100 as well as to connect the arms 2500 to the main body portion. As shown in FIGS. 68 and 72, the lock bar 2795 includes a central portion 2796 through which the sheath 2790 can extend. The lock bar 2795 also includes side portions 2797. The side portions likewise are screwed into the main body portion 2 100 to lock arms 2500 therebetween. The arms 2500 can be seen secured to the picture hanging device 2000 by the lock bar 2795 in FIGS. 65, 69, 70 and 71. The arms 2500 are removed in FIGS. 67, 68, 72, and 73 to provide clarity with respect to other parts of the picture hanging device 2000.

FIGS. 74-78 illustrate another embodiment of the picture hanging device, where like reference numerals are used to denote similar parts. The embodiment of FIGS. 74-78 is the same as that of FIGS. 63-73 unless otherwise noted. In the embodiment of FIGS. 74-78, the marker 2783 is not surrounded by a sheath 2790 which retracts. Instead, the marker 2783 is left free and leaf springs 2750 space the lower end of the picture hanging device from a wall 3500 to be marked. The leaf springs 2750 are included on each of the sliders 2700 and on the central body portion 2 100.

FIG. 74 shows an assembly of the leaf spring 2750 on one of the sliders 2700. As shown in FIG. 74, the slider has a back plate 2701 which faces a wall 3500 to be marked. The marker 2783 extends through the plate 2701. The back plate 2701 is secured by a pair of screws 2702 and one of these screws secures a leaf spring 2750 to slider 2700. FIG. 75 illustrate a leaf spring 2750 being secured to the central body portion 2 100. As shown, the leaf spring 2750 is connected to the lock bar 2795 by a screw 2702. The leaf spring 2750 then travels adjacent to a marker 2783.

Operation of the picture hanging device including the leaf springs 2750 is shown with respect to FIGS. 76 and 77. FIG. 76 shows one of the arms 2500 when the leaf spring 2750 is in a relaxed position. The leaf spring 2750 serves to space the arm 2500 from the wall 3500 and prevent the marker 2783 from contacting the wall 3500. When a user presses the lower part of the picture hanging device against the wall 3500, the leaf spring 2750 compresses, as shown in FIG. 77. This allows the lower part of the picture hanging device, including the arms 2500 to move towards the wall 3500 and the marker 2783 to make a mark on the wall 3500. Accordingly, in use, a user can place the picture hanging device against a wall 3500. The leaf springs 2750 space the rest of the picture hanging device from the wall 3500. When the user is ready to mark the wall 3500, the user presses the picture hanging device (or the lower portion of the picture hanging device) against the wall 3500. This pressing force overcomes the force of the leaf springs 2750 and the picture hanging device moves towards the wall 3500 so that the markers 2783 will contact and make marks on the wall 3500.

FIG. 78 shows various parts of the picture hanging device of FIGS. 74-78 alone. As shown in those FIG. 78, the back plates 2701 include a leaf spring receiving portion 2708. The lock bar 2795 similarly includes a leaf spring receiving portion 2798. The leaf springs 2750 have a leaf spring connection portion 2751. In order to assemble the leaf spring 2750 to the picture hanging device, the leaf spring connection portion 2751 of the respective leaf springs 2750 are disposed in the leaf spring receiving portion 2708 for the back plate 2701 of slide member 2700 and the leaf spring receiving portion 2798 for the lock bar 2795. Then screws 2702 are inserted through the leaf spring connection portion 2751 and leaf spring receiving portions 2708 to secure the leaf springs 2750 in place. In the exemplary embodiment, there are three leaf springs 2750. One leaf spring 2750 on each of the slide member 2700 of the two arms 2500 and leaf spring 2750 on the central body portion 2100 secured at the lock bar 2795. There can be more or less leaf springs in various embodiments and they can be secured at different locations. Additionally, different springs or biasing members can be used in the embodiment of FIGS. 74-78. For example, a coil spring or a rubber member can be held by screws 2702. Also, elements from this embodiment can be combined with elements from the previously described embodiments of the picture hanging device.
